If you open the Maps app, then long press on a position on the map, then select 'drive here'. Once you reach your destination, to exit the app, you must press bottom left, press stop, press bottom left and finally press exit. Yet you have still not exited the app! The map app is still active. You then need to select the maps app and close it. Phew that's a lot of buttons to press to exit an app. Anyone know a quicker way?
